Expertise Effects in Voice Recognition
Expertise Effects in Voice Recognition
Research Objectives:
Motivated by the other-race effect, the potential of an expertise effect in voice recognition is examined through manipulation of regional accent in a lineup study.
Design:
Identification of southern- and northern-accented voices by southern and northern participants was explored. Hits, misses and false alarms were recorded together with self-rated confidence.
Method:
49 Southerners and 85 Northerners took part in two lineups (southern voice, northern voice) each involving the presentation of a 60s target speaker clip, followed after a 5 minute delay by a 6 person voice lineup.
Results:
Northerners were good at identifying both the northern and southern voice. However, southerners showed a marked other-accent effect, with fewer hits and more false alarms to the northern voice than the southern voice.
Conclusions:
A parallel to the other-race effect emerged here for voice recognition. The implications of these findings are discussed with respect to eyewitness reliability.
